Specification of Letters Patent.

Patented Nov. 8, 1921.

I Original application filed October 29, 1920, Serial No. 420,527. rivid'ed nd this application filed To all whom it may concern:

, Be it known. that IJEUGIBNE SCHNEIDER, acitizen of theltepublioof 'France,. and a resident of Paris, France, have invented new and. useful Improvements in Motor rGars Having Four Drivingewheels for the Transport-of'Guns, which invention is fully set forth in thefollowing specification.

This invention has for its object to provide an improved motor-car having four 'driv-,

, ing wheels for the transport of guns shown and described in. my earlier application Serial. No. 420,527, filed October 29, .1920, of which the present application is a'division.

- This improvedcar comprises two trucks I connected together in .sucha manner as -to i be capable at, all tir'nesoibeing deflected 'simultaneouslythrough thesame angle and .in. reverse direction, relatively to the axial lwhile. the samev trucks are capable at all .times of executing atransverse rocking motion in any direction and through any angle relatively to the, same axial line.

, I The chassis of these trucks carry each, for for this purpose, a vertical pivot pin around whichtherespective-road axle'is. adaptedto ..turn.,These said chassis are provided on their innersidewith. a toothed sector receiving itsmotion from a toothed member carried by ,a connecting bar connecting'the centers of their road axles.

signed for the transport-of guns, the chassis of the front truck: carrying the engine,

i whereasthe transported load is carried on the chassis of the hind. truck. The chief improvements made inlthe car for this purpose consist of a particular construction of,

[the chassis ofitlie hind truck for utilizing a portion of the parts of the gun, both as regards the constitution ofthe, verticalpivot bar betweenthe road axles of the two trucks.-

constructed in a peculiar-manner so as to allowhthezuse of a. hindntruclr of .suitable all. times of each truck being turned through an equalangle and. in the reverse direction.

In order that the inventionmaybe more readily understood, referenceis'had to theaccompanying drawings, in whichigures l :and a 2 illustraterespectively 1n elevatlonand plan one constructional form vof the, carriage embodying the principles of my invention;

Fig. v3 isa view in partial elevation, and

,Fig. 4 is a view in plan, showing a modifica 7 road axle of thisfore-carriage; alan'dc are the .wheels. From thls ,axlethere is suspendedby means of springs-b a'chassisB that carries the engine 0- and the steering mechanism D E isa vertical pivot pin" projecting from the underside of the chassis B; The chassis, B is provided at its rear end with an arc'B provided with teeth 6 having its center in the middle, of the road axle A. "These, teeth, as will be seen hereinafter, are in constantmesh with the special driving member mountedon'the hollow bar The improved car is-more particularly de-' F I that connects the, road axlevof the forecarriage tothe roadgaxleof the hind carriage I a "The hind carriage'comprises a road axle G fitted with the wheels 9. In the middle of this road axle there is engaged a vertical pivot pin H carrying at its lowerend ahori-zontal sleeve I that serves as a bearing for the rear end of the connecting bar- F .7

The rear carriage comprises the axle and Wheels of a trail -gun carriage,-the trail J constituting the chassis. V

,f The trail tail plate is provided with an arc track rJ jadapted to bear on .a roller a mounted ,on-an arm U fixedto the connect-- ing barj'F, the track having its center inthe geometricalaxis' of thepivot-pin' The trail. plate is P Y 1 with What N0, reaesepd tednec. 5, 1918. A isthe I sector 9' having its center in the axis of pin H and is adapted to mesh with a large pinion L on a sleeve L loose on bar F. This sleeve also carries a small pinion L fast thereto which meshes with teeth b on curved member B on the fore-truck. The ratio between the numbers of the teeth of these pinions is equal to the ratio between the lengths of the radii of the toothed sectorsL and j. e V

The motion of the engine mounted on the chassis B of the fore-truck is transmitted to the road wheels a in the usual manner vthrough the medium of a differential. The

gear for transmitting the motion of the engine to the hind road wheels is effected through the medium of a vertical shaft M carrying a bevel toothed wheel m, the said 7 shaft being coaxial with the pivot pin E.

The pinion m meshes with a bevel pinion n fixed on the end of a shaft N revolving inside the hollow connecting bar F.

The rear end of the shaft N is connected by a Cardan joint n to an intermediate shaft 0 which is connected in its turn by a Cardan jointo to the differential P, whereby the motion is transmitted inthe usual manchassis B.

ner to the road wheels 9 of the hind carriage.

It will be perceived that the transverse rocking of the hind road axle relativelyfto the connecting bar F is effected by'the sleeve I rotating on the rear extension of thesaid bar, whereas the front road axle is able to turn transversely with the bar F.

The simultaneous turning of the two trucks are groduced by means of the steering device terminating in a bracket fixed to the chassis A chain T, attached at its ends t, t to the connecting bar F, is adapted to be wound on the pinion S and on a second pinion S fixed on a shaft s journaled in another bracket carried by the The pull of vented from turning, produces a turning movement of the fore-carriage, and through the medium of the teeth b and of the drivQ I ing gear L -L--L it produces also the turning movement of the teeth 7' and consequently a turning movement ofthe hind car riage. v -V The teeth I) and j, instead of being formed as spur-teeth on the sectors, may-of course be formed as crown teeth projecting from the underside of the corresponding sectors in such a manner as to engage vertically between the teeth of pinions L and L instead of enga 'ng horizontally therewith.

When it is esired to separate the combination of the fore-carriage carrying the engine and the connecting bar F from the gun,

it is sufficient to provide a. support for the trail J, such as a acknot shown, then to remove the pin of the cardan joint n and unthe pinion S upon the chain, T attached to the bar F, which latter is prescrew stop-nut w placed on the end of theshaft N. It is then possible to remove fore-carriage and the bar F which carrles with it the shaft N. The pivot pin H, to-

getherwith sleeve I carried by it, remain-in position uponthe road axle Gr, being kept back by the nut H In themodification shown in Figs. 3 and '4, the teeth 7' and the arc track J 3 are formed on a part J 4 which is independent of the trail J, and into which the trail tail plate can be fitted for transport. This independent part J 4 may, when the gun is separated from the fore-carriage and the bar F, be held upon the latter by means of two links Ji. These links occupy during transport, the position shown in full lines in which they are pinned upon the bar F.

v For the purpose of fixing the part J upon bular draw-barhaving flexible connwtions with saidtruck and carriage, adrive shaft housed in saiddraw-bar and having drlve connections with said motor and driving connections with said rear carriage wheels, said forwardtruck having a toothed sector the center of which is'in a line perpendicular to its truck axle at the center of the latter, a trail supporting plate, anti-friction bearings between saidplate and draw-bar, said plate having a curved toothed sector havin 7 its center in a line normal to the center 0 the gun carriage axle and gear connections between said toothedsectors carried by said draw-bar for transmitting steering 'move- 2.
